Santa Teresa del Almendral Airport is a small general aviation facility located near Melipilla, a city in the Metropolitan Region of Chile, roughly 60 kilometers southwest of Santiago. It is identified by the ICAO code SCTS and has no assigned IATA code, reflecting its status as a non-commercial aerodrome. The airport primarily serves private aircraft, agricultural aviation, and light general aviation operations in the agricultural heartland surrounding Melipilla. It is not a scheduled commercial passenger airport and sees limited traffic compared to major Chilean airports. Given its small scale, the facility lacks the infrastructure associated with commercial airports, including passenger terminals, airline lounges, or significant ground transport links to the city center.
